In the beginning, foam chaplets were made of 1# density foam and
used primarily in aluminum foundries. In recent years the uses
have expanded with the introduction of 2# and 3# density foam.
They are now produced loose or self-adhesive and are color coded for
thickness.
Aluminum foundries continue to be the largest users of foam
chaplets. However, ferrous foundries are finding more and more
applications.
Foam chaplets are being used in pipe foundries in the production
of fittings. They are being used in the drag of a mold to support
a large core to improve the appearance of the finished product.
The chaplets are being used in core assembly where support is not needed
during pouring. They can also be used on molding lines to prevent
core shift during movement on the line.
Core producing companies are also using our spacers as core supports
during shipping to eliminate core breakage.
